摘　　要：为探究性格差异造成的不同恐慌情绪对人员疏散进程的影响,将“OCEAN大五人格模型”与元胞自动机模型相耦合,构建性格差异化恐慌情绪的人员疏散运动模型。该模型量化分析了性格差异特征对恐慌情绪传播的影响机制,同时综合考虑恐慌情绪对行人运动速度的影响。基于所构建的模型对疏散人群中不同性格的恐慌情绪进行模拟,研究结果表明:行人个性特征中的开放性(O)、尽责性(C)和外向性(E)值较高或宜人性(A)和神经质性(N)值较低时,人群平均恐慌值会增加;性格差异化行人特征值初始比例分布的不同会影响疏散人群的疏散效率;行人的平均恐慌值和疏散时间会随着人群密度的增加而增加。To investigate the impact of personality differences on diverse panic emotions during the evacuation process,the"OCEAN Big Five personality model"was coupled with the cellular automaton model to create the personnel evacuation movement model of personality-differentiated panic emotions.This model quantitatively analyzed the influence mechanism of personality differences on the panic emotion propagation and comprehensively integrated the impact of panic emotions on pedestrian movement speed.Based on the constructed model,the panic emotions of different personalities in the evacuation population were simulated.Results indicated that higher openness(O),conscientiousness(C),and extraversion(E)values or lower agreeableness(A)and neuroticism(N)values in pedestrians′individual characteristics increase the average panic level of the crowd.Different initial distributions of personality-differentiated pedestrian characteristic values affect the evacuation efficiency of the crowd.The average panic level and evacuation time of pedestrians increase with higher population density.
